Customer Reviews for Tenacity Herbicide

It did work as advertised but the bentgrass came right back 100% in the same spots within 30 days. This product was applied professionally for two applications.

I had really high hopes for Tenacity after reading the reviews. I also purchased the recommended surfactant and blue dye. After 3 weeks, none of the weeds have shown ANY signs of dying or deformation. I even selected a secluded section of the yard that was basically entirely weed covered and doubled the recommended amount used. The weeds continue to grow at the same pace as untreated sections of my yard. Including the pump sprayer I purchased to apply this product, I spent about $150 to control the weeds in my yard. Every penny I spent appears to be a penny wasted. I would not recommend tenacity.

I followed the instructions to the word and after two weeks I just applied the second treatment only to be disappointed in the entire process. I'm disappointed in the amount of time it takes to even cause a weed to wilt. Very disappointed and would not recommend.

I was told the above mentioned products would not kill my lawn, only the clover. Followed the instructions closely. Well they were all wrong, some clover died, but so did most of the lawn. Sorry to say I can't rate less than one Star.

I ordered Tenacity and sprayed my yard. 1.5 acres. I used a 15 gallon sprayer and mixed the entire 8 oz bottle in the 15 gallons. Directions say 1 oz to 2 Gallons. I sprayed what I thought was a heavy dose on the yard. My yard turned white within about 10 days. Crab grass was white. Within another 7 days, it was completely green again and almost as thick as it was before I sprayed it. I also used 2 oz of surfantant mixed with tenacity. Very unhappy! $100 wasted!

my lawn was infested with Crab crass and other weeds. i applied Tenacity as recommended and after a week, the crab grass and few other weeds started turning white( because it is a Group 27 Herbicide) and turned my lawn into patches of white for 5-6 weeks. it looked ugly and all my neighbors asked me why white patches were appearing in my lawn. i would not use this on my lawn again. there are several other herbicides ( Group 3 or 4 herbicide) that kill the weed and dryout without turning the lawn white.

So far I am very disappointed. I put half a teaspoon of Tenacity into one gallon of water, added 1 teaspoon of surfactant, spot sprayed about a square foot of garden with some dandylion and other weed in it. Waited two weeks. No result. So I added another half teaspoon of Tenacity. Treated the same sft again. A week later no result. I really washed the two dandylion down with the stuff. What am I doing wrong??

I am on my second bottle of tenacity. I still have nimblewill which is spreading more each year. We have sprayed it every two weeks since spring. Is there any solution to this problem.

I tried this product for the first time and never will use it again. I have been doing my own lawn service for decades and have all professional equipment since my yard is over 3 acres. I bought this product to do a post emergence on some crabgrass that made it through the summer in a few spots. Well, a few dead spots of more than just crabgrass occurred. My grass was healthy and bluegrass and tell fescue. This stuff killed it all. I watched it completely turn brown over a 3 week period. I mixed it in my 60 gallon pull behind tank sprayer exactly as instructed with the required amount of sufficant. Thanks Tenacity. Now I have a ton of work to do to get my grass reseeded all while having a disgusting looking lawn.

Applied according to instructions (1 tsp Tenacity + 1 tsp surfactant + 1 gallon water) during late summer season when nimblewill starts to grow. Within 1 week nimblewill turned white.... but then after another week all grass (tall fescue) turned yellow....then brown. Nimblewill came back with a vengeance after another week, grass is dead. Applied a second time (attempting to at least kill nimblewill... 3 weeks later, my lawn looks worse than ever. Sea of dead grass and islands of thriving nimblewill. I would have been better just spraying RoundUp, at least that would kill the nimblewill and I could reseed (as I'll have to do now anyway). Very disappointed.

Applied per instructions but grass was damaged and weeds persist. Very frustrating given the price.

I had watched a video on YouTube whereby a person used Tenacity to kill weeds in his grass. I applied this product with a surfactant and Turf Mark. I used the recommended amount of each product. Unfortunately, I did not read the small print regarding certain grass that can be damaged by Tenacity. That includes Zoysia. As I watched spots in my lawn turn yellow, then white over a period of three weeks I wondered if the product had killed my healthy Zoysia grass. Fortunately, it did not. The Tenacity also did not kill the weeds. It is a very expensive product that does not work on Zoysia grass.

Tenacity did nothing to control my weeds. Better off using Spectricide weed killer.

The Tenacity didn't work on the grasses we wanted to get rid of. I wanted a kid and pet friendly solution, however this didn't work. I even sprayed area twice and made second batch stronger!

After reviewing several YouTube videos on how to rid your lawn of weeds, I decided on using Tenacity Herbicide with Hi-Yield Spreader Sticker Non-Ionic Surfactant - 8 oz, which I did purchase online. After two applications 2-weeks apart my lawn weeds continued to grow bigger, taller and stronger without any hint of illness or death. A little disappointing, since I spent nearly a $100 for the products. Now disappointed and not sure who or what to trust. Awaiting inspiration.

Bought Tenacity a couple of weeks ago and was excited to try it out based on the reviews. Unfortunately it was a huge disappointment. Added surfactant and blue dye so thatI could put it exactly in the right spots. Unfortunately, the product did not work as advertised. I still have weeds. Heck, it couldn't even kill the dandelions leave alone crabgrass. Very disappointed. In fact, I bought Moss Out and that didn't work either.

I used this to get rid of crab grass in my lawn plus some other weeds.. I followed the directions added surfactant and dye to mark the areas I sprayed. The weeds did not even slightly discolor.

it would turn crab grass and nutsedge white but then they would get their green back in a few weeks. i tried 3 applications. for this much money i would just get 2-4-d instead. that seems to kill most things and try crab grass killer.

The worst performance of any insecticide I've ever used. I followed instructions carefully and sprayed approximately 1000 sq feet for one gallon mix. did not see any sign of weeds dying. Mixed another gallon being careful to measure exact proportions as required, again no results. did a third application and applied it to 1000 sq. feet. It's been three weeks later and no weeds dead!! I have been ripped off. I paid nearly $100.00 for the tenacity, surfactant, and dye and no results. Save your money!! Don't buy this product!!

Save your money,this stuff is worthless!! Put down, not once but twice, still same results. No weeds killed, Most products out there, are BS,you need a license to buy the stuff that really works,so find someone who has access to the real weed killer , or you will just be spinning your wheels in the mud.

I'm not sure how this product gets such great reviews but it is certainly not working for me. I have mixed it carefully, used the recommended surfactant, and applied as directed. No type of weed has been killed off yet. I am on my fifth (yes, fifth) application with Tenacity, waiting two weeks between. It seems to slow them down but never kill them off. The grassy weeds, like nutsedge and crabgrass, do turn white but then come back. The broadleaf types, like wild violet and plantain, have their edges turn brown but never die off. For an expensive, professional product, I am very disappointed.
